''...after the lapse of sixty minutes, (which embrace three thousand and six hundred seconds of the Time that flies,) there came yet another chiming of the clock, and then were the same disconcert and tremulousness and meditation as before.''At the hour, everyone takes a moment of quiet to be reminded of what is to come.
The ebony clock represents the reminder and count down of death.
